Benelux: Luxembourg

The highlights reel of the past year in the Luxembourg trademark space covers two main topics: the introduction of the EU Trademark Directive (2015/2436) and the appointment of Ragnar Gustafsson as the new director general of the Benelux Office for Intellectual Property (BOIP). While practitioners have been preoccupied with the harmonisation of the directive into national law, overall there is a feeling of optimism about the opportunities that these changes present. The removal of the graphical representation requirement for example, has opened the door for registering non-conventional trademarks. Meanwhile, Gustafsson’s appointment as director general is another step towards a more innovative Benelux trademark system, which promises to be the start of an exciting new era. The consistency of this year’s rankings in comparison to last year is a  reflection of stability in the Luxembourg market, with the same players continuing to dominate.

The Luxembourg outfit is “friendly, approachable and its practitioners are at the top of their game”. Wearing the captain’s armband, Katia Manhaeve is head of a smooth operation.

When it comes to assisting global leaders across a spectrum of different sectors, the sharpshooting litigators at NautaDutilh know how to get the job done.

Being able to work with its tax lawyers for trademark restructuring matters is another weapon in the firm’s armoury.

The beating heart of the firm’s IP practice is Emmanuelle Ragot, “a truly accomplished professional who is lauded for her in-depth analysis of legal issues and meticulous nature of her work. She is a true asset for those she works with.”
